What is a 'concert overture'?

A concert overture is defined as a single-movement orchestral work that is usually intended to be performed in a concert setting rather than as part of an opera or musical theater production. This form typically serves as an introduction to a larger work or can stand alone as a self-contained piece. Often, concert overtures are composed in a free form, drawing on themes and musical ideas that evoke specific subjects or narratives, without the strict structure characteristic of symphonies or larger orchestral suites.

The focus on being a single movement highlights its concise nature, which distinguishes it from compositions that are multi-movement or designed for vocal performance, such as operas or choral works. This allows for a quick, impactful exposure to the themes and emotions the composer wishes to convey, making it an engaging addition to a concert program.
